Karl, maybe next year, I still have a lot to do. So tell me, those
Hardinge HNCs, which I also saw selling for $1k, can be refitted with
a new control easily? (easily, to me, means, not harder than my
Bridgeport). Docs available? Do they have an indexable turret?


There are several Hardinge machines running with the PPMC interface.
So, it would be quite similar and familiar to you. One detail is that
most Hardinges
have resolver feedback, but you've already seen how to do that, too.
Yes, usually an 8-position tool
turret, with a magnet/reed switch encoder. I can refer you to the guys
who have done the retrofit.
EMC2 has all the features in the tool table to handle both Z and X
offsets for lathes.
On the older machines, you really don't want to save much of the
original control,
on some of the later ones, you might keep the servo amps.
